US Patent:

20180002807, Jan 4, 2018

Filed:

Sep 14, 2017

Appl. No.:

15/704741

Inventors:

- St. Paul MN, US
Radoslav Atanasoski - Oakland CA, US
Susan M. Hendricks - Lake Elmo MN, US
George D. Vernstrom - Cottage Grove MN, US

International Classification:

C23C 14/34
C25B 1/04
C25B 9/10
C25B 11/04

Abstract:

Methods of making catalyst electrodes comprising sputtering at least Pt and Ir onto nanostructured whiskers to provide multiple alternating layers comprising, respectively in any order, at least Pt and Ir. In some exemplary embodiments, catalyst electrodes described, or made as described, herein are anode catalyst, and in other exemplary embodiments cathode catalyst. Catalysts electrodes are useful, for example, in generating Hand Ofrom water.

International Classification:

H01M 4/92

Abstract:

Nanostructured thin film catalysts which may be useful as fuel cell catalysts are provided, the catalyst materials including intermixed inorganic materials. In some embodiments the nanostructured thin film catalysts may include catalyst materials according to the formula PtMwhere x is between 0.3 and 0.9 and M is Nb, Bi, Re, Hf, Cu or Zr. The nanostructured thin film catalysts may include catalyst materials according to the formula PtCoMwhere a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and M is Au, Zr, or Ir. The nanostructured thin film catalysts may include catalyst materials according to the formula PtTiQwhere a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and Q is C or B.
